Hi,

i have an ES server with an instance already installed and running.  
That one has been deployed from rpm file (v5.6.4)  
/etc/elasticsearch/

current yml file :

```
#cluster
cluster.name: nakisa
#node
node.name: leasing
#path
path.data: /data/ESData
path.logs: /data/ESLogs
#memory
bootstrap.memory_lock: true
#ports
network.host: 10.10.10.102
http.port: 9200
http.enabled: false

```

according ES guide, we can only ES using this command : systemctl start elasticsearch.service  
I mean service name cannot be changed as it already defined in the source (in rpm package).

I am looking for a way to create a new instance (with a different name) i could host on the same server.

is it possible to start in parallel a new instance with a different name ?  
i would for example save files in /etc/elasticsearch\_sim/

do you have any suggestion ?

thanks for you help

regards

Willy

I'm running up to 6 instances of ES on the same machine. I use Puppet and the official Puppet module from Elastic to do this. OS is Debian but I would think RedHat/Centos are supported too.

This is what `/etc/elasticsearch` looks like

> /etc/elasticsearch # find .  
> .  
> ./scripts  
> ./x-pack  
> ./x-pack/users\_roles  
> ./x-pack/users  
> ./x-pack/log4j2.properties  
> ./x-pack/roles.yml  
> ./x-pack/role\_mapping.yml  
> ./es-00  
> ./es-00/logging.yml  
> ./es-00/log4j2.properties  
> ./es-00/scripts  
> ./es-00/elasticsearch.yml  
> ./es-00/jvm.options  
> ./es-01  
> ./es-01/logging.yml  
> ./es-01/log4j2.properties  
> ./es-01/scripts  
> ./es-01/elasticsearch.yml  
> ./es-01/jvm.options  
> ./es-02  
> ./es-02/logging.yml  
> ./es-02/log4j2.properties  
> ./es-02/scripts  
> ./es-02/elasticsearch.yml  
> ./es-02/jvm.options  
> ./es-03  
> ./es-03/logging.yml  
> ./es-03/log4j2.properties  
> ./es-03/scripts  
> ./es-03/elasticsearch.yml  
> ./es-03/jvm.options

Each instance has it's on SystemD unit file

> /etc/systemd # find . -name "_elastic_"  
> ./system/multi-user.target.wants/elasticsearch-es-00.service  
> ./system/multi-user.target.wants/elasticsearch-es-01.service  
> ./system/multi-user.target.wants/elasticsearch-es-02.service  
> ./system/multi-user.target.wants/elasticsearch-es-03.service

The ES binary is just installed once

As long as you run each instance on it's own port you should be fine 🙂
